The claim that “everybody's doing it’ is not usually taken as a moral justification for an act that is otherwise immoral. Children frequently use this argument on their parents, without success. Business people sometimes try this argument, for instance, in claiming that since everyone else in a given country pays bribes, they are allowed to do so also. Abraham knew better than to use that argument on the Lord. He pleaded that Sodom and Gomorrah be spared if ten just men could be found there; not that anyone was just for doing what all the rest were doing.
